Answer: (A)

A LUT is a Look-Up Table that maps input color values to new values to achieve a specific look or standard. In DaVinci Resolve, LUTs let you apply a color grade quickly by transforming how red, green, and blue values are interpreted, for example converting log footage to Rec.709 or applying a particular film look. LUTs can be 1D, adjusting each color channel separately, or 3D, remapping colors in relation across all channels for more complex results. The other options describe audio tools or a file format for exporting video, which aren’t what a LUT does.
